Microscope Cover Glass

Microscope Cover Glass are very thin square pieces of glass that are placed over a drop of liquid on a microscope slide. Due to surface tension, the liquid drop alone tends to sit in a thick dome. With a cover glass in place, the drop is flattened out, allowing the clinician to focus with high power very close to the specimen.In addition, cover glass confines the specimen to a single plane, reducing the amount of focusing necessary and protects the objective lens from immersion into the liquid. 22mm x 22mm economy grade, boxes of 200
